Microchip AVR® DB Microcontrollers (MCUs)

Low-power performance with Intelligent Analog and Core Independent Peripherals

The AVR DB family of microcontrollers (MCUs) by Microchip builds upon the low-power performance of the AVR core, offering a varied selection of Core Independent Peripherals (CIPs) and Intelligent Analog.

Featuring three on-chip operational amplifiers (op amps), this family stands out for its advanced signal conditioning capabilities. With level shifting I/O, the AVR DB family is an ideal companion microcontroller (MCU) in designs that require multiple power domains.

The AVR DB family leverages onboard CIPs and a 5V operation mode, providing increased noise immunity and reducing system latency. The Event System and Configurable Custom Logic (CCL) peripherals allow for precise real-time control. Level Shifters enables true level-shifted, bi-directional communication with devices across different power domains, making it perfect for real-time control functions in industrial control, home appliances, automotive, IoT, and many other applications.
